WILLIAM T. IRWIN, OF BONUS, ILLINOIS.

CORN-HUSKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 566,181, dated August 18, .1896. Application filed February 8, 1896. Serial No. 578,571. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM T. IRWIN, a citizen of the United States, residing at Bonus, in the counnty of Boone and State of Illinois, have invented certain new and useful Improvements in Oorn-l-Iusking Machines, of which the following is a specification.

The object of the invention is to create a forcible feed to the ears of corn in passing down the husking-rolls.

The further object of this invention is to insure the ears of corn engaging the huskingrolls and causing them to descend endwise.

In the accompanying drawings, Figure 1 is a plan view of a portion of a corn-husking machine in which the husking-rolls have been omitted for clearness. Fig. 2 is an elevation of the delivery end of a corn-husking machine. Fig. 3 is a side elevation. Fig. 4 is a vertical lengthwise section on dotted line a, Fig. 1. Fig. 5 is a side elevation of the adjustment of the upper end of the endless carrier.

The main frame of the machine consists of the lengthwise side beams 1, held separated by the cross-beam 2, and vertical beams 3 connect the side beams with the base-sills of the frame. Between the sides of the main frame are located three sets of husking-rolls 4, of any suitable construction, which are revolved in the direction indicated by the arrows shown in Fig. 2. These rolls are set on an incline, the delivery ends being lowest. Near the upper ends of the husking-rolls and over the sameis located a transverse shaft 5, and supported in boxes 6. (Shown at Fig. 5.) These boxes are fitted to move in the curved slot 7 and a set-screw 8 limits the descent of the boxes. This shaft has a connection wit-h bars 9 and 10, located outside of the main frame, their other ends being pivotally supported by stub-shafts 11 and 12, thereby supporting the shaft 5 in a pivoted frame.

The stub-shaft 12 has a sprocket-wheel 13 secured thereto and is connected by a linked belt to the driving power of the machine. A smaller sprocket-wheel 14 is secured to this stub-shaft, and is connected by a linked chain 15 with a sprocket-wheel 16, secured to the transverse shaft 5, so that the rotary movement imparted to the sprocket-wheel 13 will be transmitted to the transverse shaft 5.

The transverse shaft 5 supports three frames of like construction. A description of one will sufice for all. Upon the shaft are located two couplings 17 and 18, having a swiveled or pivotal movement in connection therewith. To these couplings are secured tubular bars 19. An extensible frame has a connection with the tubular bars and consists of a shaft 20, supported in boxes 21, from which extend screw-threaded rods 22. These rods enter the ends of the tubular boxes, and a cross-bar 23,connecting the rods, is held in place by nuts 24, placed on each side of the cross-bar. A wheel 25 is secured to the shaft 20, and a sprocket-wheel 26 is secured to the transverse shaft 5. These sprocketwheels are connected by a linked belt 27, from which at proper intervals extend teeth 28. (Shown atFigs.2 and 4.) By means of the nuts 24: the extensible frame can be adjusted to take up any slack in the chain belt. The ends'of the shaft 20 are supported in a yoke 29, from which extends a screw-threaded rod 30, passing through a transverse beam 31, receiving a nut 32 on the upper side of the beam.

The chain belt 27 is located over the center between a pair of husking-rolls. Its lower end can be vertically adjusted by means of the nut 32. onto the husking-rolls at their upper ends, and the teeth 28 of the chain belt engage them, carrying them along the husking-rolls, and after being husked force them free of the rolls at their lower ends. It will be noticed that each pair of husking-rolls have an endless chain belt provided with teeth, their lower ends made independently self-adjustable, while their upper ends are connected to the transverse shaft 5, and this shaft is vertically movable, as before described.

Should the ears of corn accumulate under the transverse shaft, it will raise, and when the accumulation has moved on it will drop to its normal position. Should two ears of corn ride each other, the teeth of the chain belt will carry the topmost ear with it until it is free of the bottom'ear, when both cars will be forced along the husking-rolls, and by this means all clogging of the huskingrolls is prevented.

Between each pair of husking-rolls is 10- The ears of corn are dropped IOO cated a fender 33, extending in the lengthwise direction of the rolls, their upper ends supported by the transverse shaft by means of the hook 34. To this fender are secured transverse strips of leather 35, those of one fender located between those of the other fender. By means of these fenders the ears of corn are thrown to either side in order that they may be operated upon by the bushingrolls. The lower ends of these fenders are adjust-ably supported by the vertical screwthreaded rod 36, passing through the trans- Verse bar 31, receiving a nut 37 on the upper end.

To the bar 10 is secured a tightener 38 for the chain belt 15.

I claim as my invention In a corn-husking machine, the combination of two or more pairs of husking-rolls, an endless carrier located between the rolls of each pair for forcing the ears along the rolls, a transverse driving-shaft, a frame for each carrier consisting of two tubular rods extending in the lengthwise direction of the carrier, a U-shaped frame supporting a wheel over which the carrier passes, the arms of the frame entering the ends of the tubular rods being screw-threaded and nuts placed upon the arms, a cross-bar located at the ends of the tubular rods, and a drive-wheel supported by the driving-shaft imparting movement to the carrier.
